Design
- Case and Dial
- The watch is housed in a one-piece steel case designed for front access to the movement. The case is reported to be free of pitting or corrosion. It features fixed lug bars, which are intended for the use of military-style pass-through straps. The dial is black with Arabic numerals and retains its original configuration. It includes a white 'skinny arrow' (broad arrow) mark and a 'Circle T' symbol, denoting the presence of tritium luminous compound. The tritium markers have developed a yellow patina consistent with the age of the watch.
